High-performance protective earth terminal with vibration-proof clamping yoke. Supports 0.05 to 4 mm² wires with automatic rail contact and 300A withstand current.
The Weidmüller WPE 2.5 is a modular Protective Earth (PE) terminal block from the W-Series, featuring robust screw connection technology with a patented clamping yoke. Engineered for TS 35 DIN rail mounting, this component establishes a reliable electrical and mechanical connection to the rail without the need for separate mounting screws, functioning as a ground contact. Constructed from Wemid insulating material (UL 94 V-0), it offers continuous operating temperatures from -60 °C to 130 °C and is fully certified for hazardous locations (ATEX/IECEx).

Integration into ATEX and IECEx Zone 1/2 environments requiring increased safety (Ex eb) protective earth connections.
Ensures compliant, spark-free grounding in explosive atmospheres where standard non-certified terminals pose ignition risks.
Establishing a centralized earth reference on TS 35 rails within high-density automation cabinets.
Mitigates electromagnetic interference (EMI) and ensures operator safety by providing a low-impedance path from conductors to the grounded DIN rail.
Terminating protective earth conductors for 3-phase motor control circuits utilizing wires up to 4 mm².
Safely diverts fault currents (up to 300 A short-time withstand) to ground, facilitating rapid breaker tripping and preventing equipment damage.
