SIEMENS 3RP25051AW30 Relay

This SIEMENS multifunction time delay relay provides twelve selectable timing functions in a single unit. It operates on a wide coil voltage range of 12 to 240V AC/DC. The SPDT contact form switches loads up to 3 A at 24, 250, or 400V AC. Adjustment is handled via a rotary dip switch for straightforward configuration.

Replaces Multiple Single-Function Timers

Instead of stocking separate relays for on-delay, off-delay, or interval tasks, this device covers all twelve functions. The jump is worth it when a control panel needs flexible timing logic without increasing component count. It reduces inventory complexity and wiring time for automation engineers and panel builders. The broad voltage input simplifies spares management across different control voltage standards.

Fits Standard DIN Rail Enclosures

The relay mounts in typical industrial electrical boxes alongside contactors, PLCs, and circuit protection. Its SPDT output frees up a pole for either NO or NC wiring as the circuit demands. The 3 A rating suits pilot duty, solenoid, and small motor starter coils directly. Ensure the control circuit voltage falls within the 12 to 240V AC/DC range for proper coil operation.

Questions about this item

What mounting style does the 3RP25051AW30 relay use?

The relay mounts on a standard DIN rail inside an electrical enclosure; no panel cut-out or chassis screws are required.

Which step is often missed when wiring the coil on this 12 to 240 V AC/DC relay?

The coil accepts both AC and DC across the full 12 to 240 V range, so the polarity of a DC supply must be observed on terminals A1 and A2.

How often should the SPDT contacts be checked on a circuit running at 3 A 250 V AC?

Inspect the contacts at regular service intervals; replace the relay if pitting, welding or excessive temperature rise is found.
