Eaton NHI-B-11-PKZ0 Bloco de contacto auxiliar, 1NO+1NC, branco, para PKZ0 208277

In industrial control panels, technicians often need to signal the status of a motor-protective circuit breaker or interlock it with other devices. The Eaton NHI-B-11-PKZ0 auxiliary contact block attaches to the front of a PKZ0 breaker and provides one normally open and one normally closed contact for exactly that purpose.

Key specifications

• Contact configuration: 1 NO + 1 NC
• Rated operational current (AC-15): 6 A at 230 V AC, 3 A at 400 V AC
• Rated operational current (DC-13): 1 A at 220 V DC
• Rated insulation voltage: 690 V
• Rated impulse withstand voltage: 6 kV
• Operating temperature range: -25 °C to 55 °C
• Terminal type: screw terminals
• Wire cross-section: 0.75–2.5 mm² (solid or stranded)
• Colour: white

Why choose it

This contact block is built specifically for Eaton PKZ0 motor-protective circuit breakers, ensuring a secure mechanical fit and reliable electrical connection. Its compact front-mount design saves space in the panel, and the screw terminals accept a practical range of wire sizes.

Ideal use cases

• Signalling the on/off state of a PKZ0 breaker to a PLC or indicator lamp
• Interlocking a motor starter with other control circuits
• Adding auxiliary contacts to existing PKZ0 installations without replacing the breaker

Good to know

The contact block is rated for use in circuits up to 690 V insulation voltage. It operates reliably in ambient temperatures from -25 °C to 55 °C, making it suitable for many industrial environments.
