346 ev-relays compact but cut off dc power current, power capsule contact relay. 150a 2a 150a 1a 60a 30a features ? small size & light weight: size 1/4, weight 1/2(compared to conventional contactors) ? no arc space is required: size includ- ing arc space 1/9 (compared to con- ventional contactors) the arc is not exposed to the outside, therefore, no arc space is not required. ? safety construction the arc is not exposed, therefore, the contactor is explosion proof and intrinsi- cally safe. ? quiet: operation noise 1/4 (compared to conventional contactors). along with the above-mentioned miniatur- ization, the operation noise has been re- duced to 70db, and, in addition, the operation noise remains unchanged when a current of 1000a or more is inter- rupted. ? high contact reliability the contact part is hermetically sealed with h 2 mixed gas, hence the contact re- sistance remains stable regardless of the ambient conditions. ? mounting direction is not speci?ed the weight of the movable parts is light, and also the restoring force is large, hence the contactor is relatively unaffect- ed by gravity. ? line-up of indicator type (150a type only) a line-up of relays with indicator that can monitor the relay operation. specifications contact characteristics type 150a type 60a type 30a type arrangement 1 form a, 2 form a 1 form a 1 form a rating nominal switching capacity (resistive load) 150a 400v dc 60a 400v dc 30a 400v dc short term current 300a (10min) (40mm 2 ) 120a (15min) (15mm 2 ) 60a (5min) (5.5mm 2 ) max. cut-off current 2,500a 300v dc (3 cycles) #1 600a 300v dc (5 cycles) overload opening/closing rating 600a 300v dc (25 cycles) 120a 400v dc (50 cycles) 120a 400v dc (50 cycles) contact voltage drop (max.) 0.1v (when current (is 150a per 1) contact set) 0.1v (when current (is 60a per 1) contact set) 0.2v (when current (is 30a per 1) contact set) nominal operating power 35w (inrush, approx 0.1s) 5w (stable) max. 5w max. 5w expected life (min. operations) mechanical 1 form a: 10 5 2 form a: 5 10 4 10 5 electrical 150a 400v dc 10 3 l/r q 1ms 60a 400v dc 10 3 l/r q 1ms 30a 400v dc 3 10 4 l/r q 1ms initial insulation resistance min. 100 m w (at 500 v dc) *1 initial breakdown voltage between open contacts ac 2,500 vrms for 1 min. *2 between contact and coil ac 2,500 vrms for 1 min. *2 operate time (at 20 c) (at nominal voltage) max. 50ms *3 reset time (without diode) (at 20 c) (at nominal voltage) max. 30ms *4 shock resistance functional min. 196 m/s 2 {20 g} *5 destructive min. 490 m/s 2 {50 g} *6 vibration resistance functional 43 m/s 2 {4.4 g} 10 to 200hz *7 destructive 43 m/s 2 {4.4 g} 10 to 200 hz *8 conditions for operation, transport and storage (not freezing and condensing at low temperature) ambient temperature C40 c to +80 c C40 f to +176 f *9 humidity 5 to 85% r.h. unit weight 150 a 1 form a: 660 g 21.16oz 150 a 2 form a: 1,100 g 38.80oz 60 a: 330 g 11.64oz 30 a: 310 g 10.93oz remarks * speci?cations will vary with foreign standards certi?cation ratings. *1 measurement at same location as "initial breakdown voltage" section. *2 detection current: 10ma. *3 nominal voltage applied to the coil,excluding bounce time. *4 nominal voltage applied to the coil. *5 half-wave pulse of sine wave: 11 ms; detection time: 10 m s. *6 half-wave pulse of sine wave: 6 ms. *7 detection time: 10 m s. *8 3 directions, each 4 hours. *9 storage: max.85 c 185 f. notes: same speci?cations as the 12 v type. #1 condition: nominal switching 100cycles, each cut off 2,500a

ev 351 notes 1. when installing the relay, always use washers to prevent loosening of the screws. tighten each of the screws within the rat- ed ranges given below. exceeding the maximum torque may result in breakage. mounting is possible in either direction. ? m8 screw (for 150 a main terminal): 10 to 15 nm ? m5 screw (150 a, 60 a, 30 a main unit mounting section) (60 a main terminal): 2.5 to 3.6 nm ? m4 screw (30 a terminal): 1.8 to 2.7 nm 2. the coils (150 a type) and contacts (30 a, 60 a, 150 a) of the relay are po- larized, so follow the instructions in the connection schematic when con- necting the coils and contacts. type 150 a has contains a reverse surge voltage absorption circuit; therefore a surge protector is not needed. we recommend installing a surge protec- tor varistor (znr) for the 30 a and 60 a types. avoid using a diode as this may re- sult in decreased cut-off capability. 3. as a general rule, do not use a relay if it has been dropped. 4. avoid mounting the relay in strong magnetic ?elds (near a transformer or magnet) or close to an object that radi- ates heat. 5. electrical life this relay is a high-voltage direct-current switch. in its ?nal breakdown mode, it may lose the ability to provide the proper cut- off. therefore, do not exceed the indicated switching capacity and life. (please treat the relay as a product with limited life and replace it when necessary.) in the event that the relay loses cut-off ability, there is a possibility that burning may spread to surrounding parts, so con- ?gure the layout so that the power is turned off within one second. when using the 30 a type, to prevent in- creases in the contact resistance, do not allow switching without any load. 6. permeation life of internal gas this relay uses a hermetically encased contact (capsule contact) with gas inside. the gas has a permeation life that is af- fected by the temperature inside the cap- sule contact (ambient temperature + temperature rise due to ?ow of electrical current). for this reason, make sure the ambient operating temperature is be- tween C40 and 80 c C40 and +176 f , and the ambient storage temperature is be- tween C40 and 85 c C40 and +185 f . 7. if the power is turned off and then im- mediately on after applying the rated volt- age (current) continuously to the relay's coil and contact, the resistance of the coil will increase due to a rise in the coil tem- perature. this causes the pick-up voltage to rise, and possibly exceed the rated pick-up voltage. in these circumstances, take measures such as reducing the load cur- rent, limiting the duration of current ?ow, and applying a coil voltage higher than the rated operating voltage (quick start). 8. main contact ratings in the ratings apply to when there is a resistive load. 9. if you are using an inductive load (l load) such that l/r > 1 ms, add surge pro- tection in parallel with the inductive load. if this is not done, the electrical life will de- crease and cut-off failure may occur. 10. when using the 150 a type, mount it as far away as possible from amateur wireless transmitters or devices that may generate large surges. to prevent malfunctioning due to high emission levels, it may be neccessary to take measures for e.m.i., such as adding a line noise ?lter or an electromagnetic shield. 11. since coil current control is per- formed, a slight amount of superimposed line noise may be generated in the input line system. if this noise must be re- moved, install a line noise ?lter. 12. be careful that foreign matter and oils and fats kind doesn't stick to the main terminal part because it is likely to cause a terminal part to give off un- usual heat. 13. avoid excessive load applied to the terminal in case of installing such as a bus bar etc., because it might give bad in?uence to the opening and closing performance. ? m8 screw terminal (150a main terminal part) terminal pulling up strength; max.100n per terminal the up-down rotation torque applied to the terminal; max.15nm 9/1/2000 all rights reserved, ? copyright matsushita electric works, ltd. go to online catalog
