DIN Rail Mounting
-- Steady & Reliable Manufacturer --
Introduction
DIN rail mounting relays are designed for installation on standard 35 mm DIN rails (EN 60715) in electrical distribution cabinets, control panels, and meter enclosures. The relay housing incorporates integral mounting clips that snap onto the rail without tools, enabling rapid installation and replacement. Terminals are configured for screw-clamp or push-in connections, supporting solid and stranded conductors from 0.5 mm² to 6 mm². The relay contacts are rated for 10A to 30A, suitable for control circuits, lighting loads, and auxiliary power switching. Magnetic latching technology provides zero standby power consumption and reduces heat generation inside the cabinet. The relay is available in 1A, 1C, and 2A contact configurations with coil voltages from 5V to 220V DC. Mechanical life exceeds 1,000,000 operations, with electrical life of ≥ 50,000 cycles at rated load.

Frequently Asked Questions
What width is available for the DIN rail relay?
The relay is available in 17.5 mm and 22.5 mm widths, compatible with standard 35 mm DIN rails and allowing efficient use of panel space.
What terminal types are available?
Standard models are supplied with screw-clamp terminals for 0.5–6 mm² conductors. Push-in terminal options are available for faster assembly without tools.
Can these relays be installed adjacent to each other without derating?
Yes. The relays are designed for zero-gap mounting on DIN rails with a 50% derating factor recommended if multiple units operate at full load continuously.
What is the advantage of magnetic latching in DIN rail applications?
Magnetic latching eliminates coil heating during steady-state operation, reducing cabinet temperature and enabling higher packing densities without thermal concerns.
