Why Choose the ABB GJH1213003R5401 KC6-40E-F-2.4-51 Mini Contactor Relay?
The ABB GJH1213003R5401, also designated KC6-40E-F-2.4-51, is a compact 4-pole mini contactor relay designed for reliable control-signal switching in industrial automation, machinery and building control systems. Part of ABB's established KC6 mini contactor relay range, it provides four normally open auxiliary contacts and uses flat-pin Faston connections for quick, secure wiring.
The KC6-40E-F-2.4-51 operates from a 17–32 V DC control circuit and uses a low-consumption 2.4 W DC coil. Its DC-operated design provides noiseless and hum-free switching, making it particularly suitable for PLC interfaces, automation equipment and electrical control cabinets where low power consumption and dependable operation are important.
With its 4NO auxiliary contact configuration, conventional free-air thermal current of 6 A and control-signal switching capability up to 3 A at 400 V AC under AC-15 utilisation, the GJH1213003R5401 provides dependable performance in demanding control applications. Compact dimensions of approximately 57.5 × 52.5 × 46.5 mm make it especially useful where panel space is limited.

Reliable Control Switching for Industrial Automation
Mini contactor relays such as the ABB KC6-40E-F-2.4-51 provide compact electromechanical switching between industrial controllers and control circuits. Applying a control voltage within the 17–32 V DC range energises the coil and closes the four normally open auxiliary contacts, allowing multiple signalling, sequencing or interlocking functions to be operated simultaneously.
The flat-pin Faston connections distinguish this version from screw-terminal KC6 variants, providing convenient plug-in connections with good resistance to vibration. Combined with its low 2.4 W coil consumption, hum-free operation, compact dimensions and 10-million-cycle mechanical durability, the GJH1213003R5401 provides a dependable switching solution for modern industrial automation systems.
Typical Applications
- PLC output and interface circuits.
- Industrial automation and machinery control panels.
- Control-signal switching and multiplication.
- Electrical sequencing and interlocking circuits.
- Conveyor and material handling equipment.
- Residential, commercial and industrial building control systems.
