Auxiliary contacts NHI-B-11-PKZ0 208277

Auxiliary contacts for circuit breakers – reliable signaling and control

NHI-B-11-PKZ0 auxiliary contacts are a key element extending the functionality of Eaton Moeller® NHI series motor starters. They enable the implementation of additional control and signaling circuits, increasing the safety and efficiency of the installation. Front-mounted, they provide convenient access and ease of installation.

Construction and application

These auxiliary contacts are designed for top mounting, which facilitates their integration with the circuit breaker. Made of high-quality materials, they guarantee long-lasting and trouble-free operation even in demanding conditions. The use of screw connections ensures secure and durable electrical connections, minimizing the risk of errors in the circuit. They are ideal for applications requiring reliable signaling of the circuit breaker status or control of additional devices.

Key features and benefits

• Versatility: Availability of one normally open (NO) and one normally closed (NC) contact allows for flexible adaptation to different control schemes.
• Safety: Compliance with safety standards (CE, CSA, UL, IEC/EN 60947-4-1) ensures protection of the installation and users.
• Durability: Tested for electrical endurance (100,000 operations) and mechanical endurance (100,000 operations) – a guarantee of long life.
• Secure connections: Screw connections minimize the risk of wires loosening and ensure stable circuit operation.
• Compact dimensions: Small dimensions (12 mm depth, 35 mm height, 45 mm width) allow for mounting in limited space.
• Wide voltage range: Possibility of operation at a rated operating voltage of up to 440 V AC and 250 V DC.
• Rated current: Rated operating current Ie for AC-15 at 230 V is 1 A, which allows for controlling various receivers.

Thanks to these features, NHI-B-11-PKZ0 auxiliary contacts are a reliable solution for both professional installers and end-users looking for a safe and effective way to expand the functionality of their Eaton Moeller® motor starters.
