Eaton NHI11-PKZ0 Auxiliary Contact Block, 1NO+1NC, Screw Terminals, for PKZ0/PKZM0/PKE

With a rated insulation voltage of 690 V and compliance with IEC/EN 60947-5-1, the Eaton NHI11-PKZ0 auxiliary contact block delivers reliable signal and control functionality for motor protective circuit breakers. This side-mounting module provides one normally open (NO) and one normally closed (NC) contact, enabling precise status indication and interlocking in industrial control circuits.

Overview

The NHI11-PKZ0 is engineered for seamless integration with Eaton PKZ0, PKZM0, and PKE motor protective circuit breakers. Its compact design and screw terminal connections ensure secure wiring and long-term stability. The contact block is suitable for use in demanding environments, with an operating temperature range from -25 °C to +55 °C and storage range from -40 °C to +80 °C.

What stands out

• Dual contact configuration: 1 NO + 1 NC for versatile control and monitoring.
• High rated insulation voltage (Ui) of 690 V for safe operation in industrial systems.
• Rated impulse withstand voltage (Uimp) of 6 kV provides robust protection against transient overvoltages.
• Screw terminals accept solid, stranded, and fine-strand conductors up to 2.5 mm², simplifying installation.
• Side mounting saves space and allows quick attachment to compatible breakers.
• IP20 terminal protection guards against accidental contact with live parts.
