HR402CA110 Lovato MINIATURE RELAY 2C/O 5A 110/120VAC

Why Choose the Lovato HR402CA110 Miniature Relay?

The Lovato HR402CA110 is a compact general-purpose miniature relay designed for switching and interface duties in industrial control, automation and electrical panel applications. Featuring 2 changeover (2C/O) contacts, it provides flexible switching of two independent circuits from a single relay coil.

The HR402CA110 uses a 110/120 V AC coil and provides a rated contact current of 5 A. Its DPDT contact arrangement gives both normally open and normally closed switching options, making the relay suitable for control logic, signal interfacing, auxiliary switching and isolation between control circuits.

As part of the Lovato Electric HR40 series, the HR402CA110 is designed for use with compatible relay sockets, allowing straightforward installation, replacement and maintenance in control panels. Its compact plug-in construction makes it a practical choice for machinery, building automation and general industrial control systems requiring dependable electromechanical switching.

Flexible Electromechanical Switching for Control Systems

General-purpose relays such as the Lovato HR402CA110 allow a relatively low-power control signal to operate electrically isolated switching contacts. With 2 changeover contacts, the relay can simultaneously switch two circuits between normally closed and normally open states, providing considerable flexibility for machine logic, interlocking, signalling and interface applications.

The plug-in miniature relay format is particularly useful in industrial control panels because the relay can be removed from its socket without disturbing the permanent field wiring. This simplifies testing and replacement while allowing compatible sockets and accessories to provide an organised, serviceable interface between the relay and panel wiring.

Typical Applications

• Industrial control and automation panels.
• Machine control circuits.
• PLC output interfacing.
• Contactor and auxiliary device control.
• Alarm and signalling circuits.
• Building automation systems.
• Electrical interlocking and control logic.
• General-purpose switching using a 110/120 V AC control supply.
