Same Day Shipping

HC: Identifies the relay series (General Purpose Miniature Relay).

4: Indicates the number of contacts: 4 Form C or 4PDT (Four Pole Double Throw).This means the relay has four independent switching mechanisms, each with a Common, a Normally Open (NO), and a Normally Closed (NC) contact, providing a total of 14 pins for wiring (4 common + 4 NO + 4 NC + 2 coil pins).

H: Specifies the standard Plug-in mounting type, designed to be used with a corresponding socket.

AC220-240 (often sold as HC4-H-AC240V): This specifies the Nominal Coil Voltage.⁴

• Coil Type: AC (Alternating Current), Non-Latching.

• Nominal Voltage: The coil is designed to operate with either 220 V AC or 240 V AC (50/60 Hz).⁵

• Nominal Coil Current (at 60 Hz): Approximately 6.5 mA.

• Nominal Operating Power: 1.2 VA (at 60 Hz).

Contact Material: Typically Silver Nickel (AgNi), often gold-flashed for reliable switching of low-level loads.⁶

Contact Rating: 5 Amps (A) at 250 V AC (Resistive Load).⁷

Maximum Switching Power: 1,250 VA.

Operating Time: Approximately 20 milliseconds (ms).⁸

Expected Life (Mechanical): Up to 5 million operations for the AC type.

Typical Applications: Control panels, machine tools, welding equipment, power supply systems, and various office/household appliances
