ABB ZM-40-PKZ2

The ABB ZM-40-PKZ2 is a high-reliability thermal trip module designed for motor protection and control. It integrates a single-circuit breaker power contact, 10-class thermal overload protection, and current-limiting short-circuit protection, effectively preventing motor overload or short-circuit faults.

Specifications

• Current range: 32A to 42A.
• Setting range: 8.5 to 14 times the rated current.
• Voltage compatibility: Complies with UL/CSA standards, supporting multiple voltage configurations.
• Structural features: Modular design, mountable on a PKZ2 base, with support for side-mounted auxiliary contact blocks and undervoltage release.
