SCHNEIDER RUMC21P7 Product Description

Overview

SCHNEIDER RUMC21P7 is a Harmony RUM series plug-in universal relay manufactured by Schneider Electric. The SCHNEIDER RUMC21P7 features 2 changeover contacts, 230V AC coil and cylindrical pin design, used for signal switching and load control in industrial automation circuits. This RUMC21P7 plug-in relay serves as a reliable Schneider Harmony RUM series relay, widely used for interlock, signal transfer and small load switching in control cabinets and automation systems of the Schneider Harmony RUM series relay.

Features

This SCHNEIDER RUMC21P7 adopts transparent housing and lockable test button for manual contact testing and maintenance for the Schneider Harmony RUM series relay. It uses AgNi contact material, stable performance under frequent switching cycles. The cylindrical pin structure is matched with dedicated RUM socket for quick plug and replacement. It supports optional accessories including surge suppression modules and bus jumpers. The SCHNEIDER RUMC21P7 has compact size, easy layout on DIN rail, suitable for long-term stable operation in industrial EMC environments of the RUMC21P7 plug-in relay.

Specs

The SCHNEIDER RUMC21P7 series: Harmony RUM universal plug-in relay. Contact configuration: 2 C/O (DPDT). Rated thermal current: 10A. Coil voltage: 230V AC. Pin type: cylindrical pin. Rated insulation voltage Ui: 250V IEC. Rated impulse withstand voltage Uimp: 4kV. Operating temperature range: -40°C ~ +55°C. Mounting: matched socket, DIN rail installation. The SCHNEIDER RUMC21P7 complies with IEC 61810, CE and UL standards as a RUMC21P7 plug-in relay.

Principle

SCHNEIDER RUMC21P7 works by electromagnetic actuation principle. When voltage is applied to the coil, the generated magnetic field attracts the armature and switches the contact state. The SCHNEIDER RUMC21P7 changeover contacts switch to transmit control signals or supply power to small loads. When coil power is cut off, spring force resets the contacts back to original state. The test button can manually simulate contact action without energizing the coil. The electromagnetic switching structure of the Schneider Harmony RUM series relay realizes flexible signal transmission for control loops.

Applications

This SCHNEIDER RUMC21P7 is widely used in packaging machinery, conveyor systems, pump and fan control, PLC signal isolation and general automation panels. It is applied for interlock logic, indicator light driving and low-power load switching. It is used for spare replacement and retrofit of existing Schneider RUM relay control circuits. The SCHNEIDER RUMC21P7 delivers dependable signal switching and auxiliary control for low voltage automation systems as a proven RUMC21P7 plug-in relay.
