Liebert E-2500 Contactor

The Liebert E-2500 Contactor is a high-performance 3-pole electrical switch specifically engineered for mission-critical cooling infrastructure. Designed primarily for Liebert Mini Mate 2 units and similar precision environmental control systems, this contactor features a 24V AC coil and is rated for 50A inductive loads (with some specifications supporting up to 63A). As a vital component in server room cooling and industrial HVAC setups, the E-2500 manages power flow to compressors and blower motors with high-cycle reliability.

For technicians in the field, this direct replacement contactor (often cross-referenced as 59YE34) ensures electrical continuity and system stability in demanding 24/7 environments. Its robust construction and compact 3-pole design facilitate seamless integration into existing Liebert control cabinets without technical modifications. By maintaining precise switching for high-amperage components, the E-2500 helps prevent premature motor failure and optimizes the operational efficiency of specialized AC equipment.

Key Benefits

• High Amperage Rating: Robust 50A-63A capacity handles the heavy startup and running currents of industrial compressors and motors.
• Reliable 24V Activation: Features an integrated 24V coil for standard low-voltage control circuit integration.
• Industrial-Grade Contacts: Built with high-quality materials to reduce arcing and extend the service life of critical switching points.
• Compact Triple-Pole Design: Provides simultaneous switching of three-phase power lines within a space-saving footprint.

Common Questions

Is the coil included with the Liebert E-2500?
Yes, this unit is a complete contactor assembly that includes the 24V AC coil required for actuation.

Will this work as a replacement for other 3-pole 24v contactors?
While the E-2500 is an OEM-spec part for Liebert brand equipment, it can replace other contactors with matching amperage ratings, voltage requirements, and physical mounting footprints.

What symptom indicates this part needs replacement?
Common indicators include a humming or chattering noise from the control cabinet, pitted or welded contacts, or a failure of the compressor/blower to engage when 24V is present at the coil.
