PKZ2/ZMR-2.4/S Eaton Motor Protective Circuit Breaker

The PKZ2/ZMR-2.4/S is a 3-pole motor protective circuit breaker rated at 2.4 A, configured as a manual motor starter. It integrates the PKZ2 basic module, ZMR-2.4-PKZ2 overload relay (thermal trip range 1.6–2.4 A), S-PKZ2 high-capacity magnetic contactor, and C-PKZ2 DIN rail mount. Magnetic trip occurs between 20 A and 35 A. It supports motors up to 1/2 HP at 230 V and 1 HP at 460 V. Certified to UL 508 and CSA 22.2 standards, it is HP-rated and approved for group installations per NEC 430-53(c) and CEC Rule 28-206. This enables multiple motors to share one branch-circuit protective device in compliance with applicable electrical codes.
