Siemens 3RP1533-1AQ30 Off-delay Timer Relay Ac Dc

Product Description

The SIEMENS 3RP1533-1AQ30 is an off-delay timer relay designed for use in industrial and commercial control circuits. Off-delay relays hold their output contacts in the energized state for a set time period after the control signal is removed, then release — making them essential for sequencing shutdowns, motor run-on applications, and process timing. This relay accepts both AC and DC control voltage inputs, giving it broad application flexibility across different panel configurations. Licensed electricians and industrial control technicians are the primary installers of this device.

The 3RP1533-1AQ30 is suited for industrial automation panels, HVAC control systems, and process equipment where timed de-energization of a load is required after a signal loss. Its compact DIN-rail-compatible form factor fits standard control panel layouts in both new construction and retrofit installations. The AC/DC input compatibility makes it a practical choice when panel voltage supply types vary across a facility or job site.

Key Features

• Off-delay timing function holds output contacts closed after control signal is removed
• Accepts both AC and DC control voltage for broad panel compatibility
• Compact form factor suitable for DIN-rail mounting in standard control enclosures
• Lightweight construction at 0.3 pounds for easy panel integration
• Consistent timing performance for motor run-on, fan delay, and process sequencing applications

Compatibility

Designed as an OEM-style off-delay timer relay for use in industrial and commercial control panels requiring AC or DC compatible timing relay functions.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the NEC and applicable local codes. De-energize and lock out the control panel before removing or installing the relay. Verify control voltage type and magnitude match the relay input specifications before applying power. Do not exceed the relay contact ratings for the load circuit being switched.
