Schneider Electric Solid State Relays SSM1A455BD

The Solid State Relay SSM1A455BD from Schneider Electric is designed for single-phase applications with a load current rating of 55 A. It operates with a control voltage range of 4 to 32 V DC and can switch output voltages from 48 to 660 V AC. The relay features a normally open (NO) contact configuration and is suitable for DIN rail mounting. This relay has a maximum on-state voltage drop of less than 1.7 V and can handle surge currents up to 1000 A for 16.6 ms. It offers a response time of 0.5 cycles for both turn-on and turn-off operations. The device is rated for a dielectric strength of 4 kV AC and has an insulation resistance of 1000 MOc at 500 V DC. The SSM1A455BD is compliant with several standards, including UL 508 and IEC 60950-1, and is marked with UL, CSA, EAC, CE, and RoHS certifications. It operates effectively in ambient temperatures ranging from -40 to 80 ¬8C and has an IP20 protection rating. The relay is equipped with a green LED for local status indication and features screw terminals for easy connections.
