Enclosed Power Relay for DIN Rail Mounting

This Schneider Electric RPF2BJD relay provides DPDT switching in a sealed square base designed for DIN rail and top flange installation. It operates from a 12V DC coil and carries a 30 A rating on its normally open contacts, making it suited for industrial control panels and automation equipment that require reliable load switching.

Sealed Construction with Tab Terminals

The enclosed body protects internal contacts from dust and moisture while eight 0.25 in flat tab terminals simplify wiring. Coil power draw is low at 12V DC, and the sealed design eliminates moving-part noise during operation. Contact ratings reach 30 A at 250/277V AC on the normally open side and 25 A at 28V DC, with a 3 A normally closed rating for both AC and DC circuits.

Replaces Open-Frame or Lower-Current Relays

This unit upgrades installations that previously used unsealed relays or devices rated below 30 A, adding environmental protection and higher carry capacity in the same square footprint. The jump is worth it when panels face humidity, debris or vibration, or when motor loads up to 3 hp at 240V AC must be switched reliably. Builders needing a status indicator or push-to-test button should look elsewhere.

Questions about this item

How is the relay mounted on a DIN rail and top flange, and what step is often missed?

Snap the base onto a standard DIN rail and secure the top flange with screws; the step often missed is tightening the flange screws after the rail clip engages.

Which parts will need replacement after extended switching cycles?

The sealed relay has no user-serviceable parts; when the 30 A contacts reach end of life the entire unit is replaced.

At what load does the coil or contacts hit their thermal limit first during continuous operation?

The 30 A @ 250/277 V AC (NO) rating is the highest continuous current; sustained loads at that level will reach the contact temperature limit before the 12 V DC coil does.
