Pilla Electrical PILLA-PILNOCB Normally Open Contact Block

Product Description

The PILLA ELECTRICAL PILLA-PILNOCB is a single-pole, normally open (N.O.) contact block designed for use with stackable pushbutton and selector switch operator assemblies. This contact block maintains an open circuit at rest and closes the circuit only when the actuator is depressed or engaged. It is a core switching element used in industrial and commercial control panels, motor starters, and machine control circuits. Electricians and control panel builders install this type of contact block as part of modular operator assemblies where multiple contact configurations are required in a compact footprint.

This contact block is suited for industrial control wiring applications where low-voltage or line-voltage pilot circuits require a normally open switching element. Its stackable design allows multiple contact blocks to be combined onto a single operator body, enabling multi-function control from one mounting cutout. Typical install scenarios include motor start circuits, indicator light interlocks, and safety interlock wiring in control enclosures.

Key Features

• Normally open (N.O.) contact configuration closes circuit on actuation
• Stackable design allows multiple contact blocks on a single operator
• Modular construction supports field assembly without special tooling
• Compatible with standard pushbutton and selector switch operator bodies

Compatibility

Designed as an OEM-style stackable contact block for use with compatible Pilla pushbutton and selector switch operator assemblies requiring normally open contact elements.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize and lock out the control panel before removing or installing contact blocks. Snap the contact block onto the operator body according to the manufacturer assembly sequence and verify secure mechanical engagement before re-energizing. Do not exceed the rated voltage or current of the contact block in the final circuit application.
