Eaton VHI20-PKZ01 contacto auxiliar avançado 240 V AC 1 A 2 NO para PKZ0/PKE 278495

In motor control applications, the Eaton VHI20-PKZ01 auxiliary contact mounts directly onto PKZ0 or PKE motor protective circuit breakers to provide early-make signalling before the main contacts close. This leading contact is used by panel builders and machine OEMs to sequence control circuits, ensuring auxiliary functions activate ahead of the main power path.

Key specifications

• Contact configuration: 2 normally open (2 NO)
• Rated operational voltage: 240 V AC
• Rated operational current (AC-15): 1 A
• Mounting: side mounting, clip-on
• Terminal type: screw terminals
• Wire cross-section: 0.75 mm² to 2.5 mm²
• Operating temperature range: -25 °C to +60 °C
• Degree of protection: IP20 (terminals)

Why choose it

The leading contact design ensures that auxiliary circuits are established before the main contacts close, which is critical for interlocking and signalling in motor starters. The clip-on side mounting allows quick installation without tools on compatible Eaton breakers, reducing wiring time in control panels.

Ideal use cases

• Motor control centres requiring early auxiliary contact closure
• Interlocking circuits for reversing starters
• Status indication for motor protective breakers
• Automation panels using PKZ0 or PKE breakers

Good to know

The contact is rated for 240 V AC operation at 1 A, suitable for low-power control signals. It is designed for use with Eaton PKZ0 and PKE series motor protective circuit breakers, ensuring a secure mechanical fit.
