SOCOMEC 3999 0022

Socomec 39990022 Auxiliary Contact Block

Description

The Socomec 39990022 is a high-quality pre-break auxiliary contact block featuring two normally open (2NO) contacts. It is specifically designed as an accessory for the SIRCO M and MV series of load break switches. This module enables advanced control and signaling by actuating before the main power contacts, making it ideal for interlocking, status indication, and other control circuit applications where early signaling is required.

FAQ

Question? What is the purpose of a “pre-break” or “early-make” contact?

A pre-break (or early-make) contact changes its state slightly before the main power contacts of the switch operate. This is critical for control circuits, allowing a control system (like a PLC) to know a switch is about to operate before the main power is cut or applied.

Question? How is this contact block installed on a SIRCO M switch?

The 39990022 module is designed to clip directly onto the side of the SIRCO M or MV switch body. It requires no special tools for installation, ensuring a quick and secure fit.

Question? What are the electrical ratings for these auxiliary contacts?

While specific ratings depend on the application voltage, typical ratings for such contacts are around 10A for AC-15 (e.g., at 240V AC) and lower for DC-13 inductive loads. Always consult the official Socomec datasheet for the SIRCO M series for precise electrical characteristics.
