Product Overview
G. General Electro-Components HKH-3A Plug-In Control Relay – Unused NOS
This is a G. General Electro-Components HKH-3A general-purpose plug-in control relay with a 120 VAC coil and a 10 amp contact rating, intended for industrial control-panel applications.
Relays like this lived quiet, dependable lives inside cabinets where logic mattered more than attention. Built to be replaced without rewiring, the HKH-3A reflects a control philosophy focused on uptime, serviceability, and straightforward electrical design.
Product Condition
Unused, new old stock in the manufacturer’s original packaging. The relay shows no signs of field installation or electrical service.
Product Overview
The G. General Electro-Components HKH-3A is part of a family of plug-in control relays commonly used in industrial automation, HVAC systems, and OEM machinery. Designed for panel use with a matching socket, it allows quick replacement without disturbing fixed wiring.
This relay is suited for control-duty switching such as energizing contactor coils, pilot lights, alarms, and similar loads. It is not a power contactor and should be applied using standard control-circuit design practices.

Frequently Asked Questions
Is this relay used or refurbished?
No. This relay is unused new old stock and remains in the manufacturer’s original packaging.
What voltage coil does this relay use?
This HKH-3A relay uses a 120 VAC control coil designed for standard 50/60 Hz control power.
What loads can the 10 amp contacts handle?
The 10 A rating applies to resistive loads at 120 VAC. Inductive loads such as solenoids or coils should be appropriately derated per standard control design practices.
Is the contact configuration confirmed?
Public listings describe this relay family as DPDT with an 8-pin plug-in base. Exact internal configuration should be verified against original G. General Electro-Components documentation or by inspection if critical.
Does this include a socket?
No socket is included. This relay is intended to be used with a compatible G. General Electro-Components or equivalent plug-in relay socket.
Built for cabinets where reliability mattered more than novelty, this HKH-3A waited its turn on a shelf. Its working life now resumes wherever dependable control logic is still valued.
