PHOENIX CONTACT USA Monitor - Relay Output 2906253

The EMD-BL-PTC-PT is a temperature monitoring relay for motor windings using up to six PTC thermistors per DIN 44081 and DIN 44082, with short-circuit detection and push-in terminals. It operates on 230 V AC (range 195.5-253 V AC) and utilizes a 1 A floating changeover contact rated for 250 V AC and 1250 VA. The relay drops out at ≥3.6 kΩ and picks up at ≤1.6 kΩ, with a response delay below 100 ms and recovery time over 300 ms. It features auto-reset, a 17.5 × 89.5 × 65.5 mm footprint, and DIN rail mounting per EN 60715. The housing has IP40 protection, operates from -25 °C to 55 °C, and meets CE, Low Voltage, and EMC directives with immunity and emission compliance to EN 61000-6-2 and EN 61000-6-3, under IEC 60947-5-1. Electrical service life is 1×10⁵ cycles, and mechanical life is 15×10⁶ cycles.
