Eaton / Moeller Series
4A, 3P, manual motor starter, self-protected with overload trip and high-capacity contactor, UL/CSA
The Moeller PKZ2/ZMR-4/S is a self-protected manual motor starter designed to deliver reliable overload and short-circuit protection. This unit combines the PKZ2 basic module, ZMR-4-PKZ2 overload relay (adjustable 2.4–4 A), S-PKZ2 high-capacity magnetic contactor, and C-PKZ2 DIN rail mount. With a magnetic trip range of 35–55 A, it supports motors up to 1 HP at 230 V and 2 HP at 460 V. UL listed and CSA certified, it is approved for group installations per NEC 430-53(c) and CEC Rule 28-206, allowing multiple PKZ2 starters to share a single branch circuit protective device. This reduces wiring, cost, and panel space requirements while ensuring safety and compliance in industrial applications.
