31CSP2E220 - SEQUENCE RELAY CSP2E 220VAC

Why Choose the 31CSP2E220?

Lovato 31CSP2E220 is a CSP2E start-up priority change relay designed for dependable duty/standby motor control. This 11-pin plug-in device (socket S11) provides two relay outputs and operates from a 220VAC supply, managing start-up priority and enabling possible starting of a stand-by motor. With robust 5 A Ith switching and 4 kV impulse withstand, it suits industrial control panels requiring reliable sequencing and resilience.

Built to perform across -20 to +60 °C, this compact 150 g relay delivers consistent operation in varied environments. Conformance to IEC/EN 60255-5 underpins electrical endurance, while the plug-in format streamlines maintenance and replacement. Ideal where start-up priority must be enforced and a standby motor can be brought online, the CSP2E range integrates cleanly into existing 220VAC control architectures.
