Woonyoung WYZS Busbar-Type Zero-Phase Current Transformer for MCCB, 200 mA / 100 mV

Busbar-type zero-phase current transformer (200 mA / 100 mV) that mounts directly on MCCB bus terminals (25-35 mm bus size), in 1P2W, 3P3W and 3P4W versions.

Key features

Primary conductor passes through the core; detects zero-sequence (earth leakage) current
Silicon steel core with good permeability for precise output characteristics
Self-extinguishing ABS flame-retardant resin case (ABS and PC)
Lightweight construction without internal filler
Terminal cover for safety
KC and CE marked
