Introduction
Designed specifically to protect substation equipment from dangerous spikes and transients, the EI-MSB10-400 instrumentation surge protector absorbs the event utilizing a multi-stage transient suppression scheme, before critical equipment is reached. This unit is very low cost and is essential to significantly improve equipment reliability.
- Designed to protect sensitive equipment from the damaging effects of lightning strikes and/or industrial switching surges in single phase AC networks up to 320 V AC (L-N / L-G), and DC networks up to 400 V DC.
- The EI-MSB10-400 instrumentation surge protector is connected by wires in parallel with the network to be protected. It can be easily mounted on a wall or plate with self-adhesive tape.
- The unit’s LEDs alert you to protection status (see image below).
