Omron G7Z Series Power Relay, 12V Coil Voltage, 40A Switching Current - G7Z-4A-20Z-R 12VDC

This power relay is a Compact electromechanical switching device designed for industrial control and automation tasks where high current switching and DIN rail or screw mounting are required. It operates from a 12V DC Coil and is intended for integration in electrical cabinets and control panels that demand four independently switched poles in a normally open configuration.

Features and Benefits:

• 12V DC Coil consuming 3.7 W improves compatibility with common control supplies
• 39 Ω Coil resistance enables predictable Coil drive current
• Four-pole normally open contacts permit simultaneous multi-circuit switching
• Silver-alloy contacts support high current operation up to 40 A
• Rated for switching up to 480 VAC for AC circuits
• Screw terminals and DIN rail mounting simplify secure installation

Applications

• Suitable for motor starter control in industrial panels
• Ideal for switching multiple loads in automation racks
• Used with distribution circuits requiring 40 A contact ratings
• Can be used for DC load switching up to 125V DC
• Suitable for retrofit into DIN rail assemblies in electrical enclosures

What temperature range can it operate within?

It is specified for use between -25 °C and 60 °C, covering typical indoor industrial environments.

How does the contact resistance affect system performance?

The contact resistance of 400 mΩ influences voltage drop and heating under load, important for thermal planning at high currents.

What mounting options are available for panel integration?

It accepts screw-type connections and can be fixed onto a standard DIN rail to suit varied enclosure arrangements.

What construction detail aids long-term switching at high current?

Contacts are MADE from a silver alloy to handle frequent switching and reduce contact wear when switching heavy loads.
