- Sensitive phase-failure protection; trips rapidly on single phasing to prevent motor burnout.
- Rotary knob with padlock provision for lockout/tagout (마음) safety isolation.
- Built-in TEST pushbutton for manual mechanical trip testing.
- Wide range of add-on accessories: 보조 접점, fault trip contacts, 저전압 릴리스, 션트 여행, side busbars.
- DIN 레일 장착; 모듈식 디자인, directly combinable with DILM contactors to form MSC motor starter units.
✅ Variants with Suffixes (Same Current Rating)
PKZM0-16: Standard screw terminals (주문 번호. 046938)
PKZM0-16-EA: EA export version
PKZM0-16-SPI32: Screw terminals on line side, push-in spring terminals on load side
PKZM0-16-GVP2: Bulk packaging version
✅ 선택 & Equivalent Cross Reference
Domestic equivalents: Delixi CDP6-16, Chint NS2-25 (10–16 A)
Next higher rating in series: PKZM0-20 (16～20 A)
메모: PKZM0 is an integrated breaker; it cannot be used solely as an overload relay. Use ZB series if only thermal overload protection is required.
✅ Troubleshooting Guide
- Trips immediately with no load: Check if current setting is too low, 위상 손실, or mechanical trip mechanism jamming.
- Instant trip on motor startup: Short-circuit protection triggered; inspect motor winding short-circuit or cable fault.
- Slow trip under sustained overload: Normal Class 10 inverse-time behaviour; if tripping frequently under heavy load, increase the current setting or upgrade to a higher-rated model.

6) 선택 지침
- Require phase-failure protection → Choose PKZM0; No phase-loss risk & cost-sensitive → Choose PKZM01.
- Remote tripping → Select A-PKZ0 shunt trip; Anti-restart on power failure → Select U-PKZ0 undervoltage release (cannot mount both).
- Frequent on-site wiring → Prefer -PI push-in terminal version; General installation → Standard screw terminal model.
