Hard-wire AC Power Surge Protector
BPS-MSB10-120, BPS-MSB10-400, BPS-MSB10-480

...................................................................................................................

 

The BPS-MSB10 is a general duty AC Surge Protection Device (SPD) for high risk electrical and electronic applications. The BPS-MSB10 provides protection against the direct and indirect effects of lightning and is particularly useful where space is limited.




This device is designed for single and two phase applications up to 480Vac with a surge current handling of 18kA 8/20us. The BPS-MSB10 offers, very low leakage current to ground, produces no follow on current and has a low residual clamp voltage.

The BPS-MSBS10 provides wire connection leads for parallel wiring, mounting flange to facilitate easy surface installation, high quality metal oxide varistors with integral thermal disconnection compliant to UL-60691 and real-time visual fault indication.
