Selection Notes

Unlike the WMP variants in this frame, this is a complete fixed breaker with front, bolted terminals - no separate cradle or fixing part is needed, which simplifies a panel where drawout racking is not required. The Ekip Dip LSI release protects all four poles with overload, short-time delay and instantaneous stages, and the neutral pole carries the full 100% of Iu for four-wire systems. Pick the 3-pole fixed version instead where the installation has no neutral conductor to switch.
