H3Y-2 / H3Y-4 Power-On Delay Timer Relay

Add a defined power-on delay to a suitable control circuit with an H3Y timer relay. Choose the relay type, timing range and supply version that match the circuit design.

• ✅ Set a delay with the front knob - choose an appropriate range for the required sequence.
• ✅ Match the control supply - separate AC and DC voltage options are listed.
• ✅ Choose the installation package - base-included options are marked separately.

Three Choices Matter: Relay Type, Time and Supply

H3Y-2 and H3Y-4 versions must be matched to the required contact arrangement and socket. Select the timing range as well as the voltage; a seconds-range version is a different selection from a minutes-range unit.

Check the exact pinout, contact rating, AC/DC supply and base before installation. The phrase 'with Base' identifies packages that include a socket; unmarked versions should not be assumed to include one. Qualified electrical installation is required.
