SLONGELE TM Adjustable MCCB (Thermal-Magnetic Adjustable Molded Case Circuit Breaker) is built for low-voltage power distribution where engineers need stable circuit protection plus flexible current adjustment. This category covers 200A–1250A models commonly used in main feeders, distribution panels, MCC rooms, and industrial switchboards.
The thermal element provides dependable overload protection, while the magnetic element responds quickly to short-circuit faults, helping protect cables, equipment, and downstream circuits.
A key benefit of this series is the 0.7–1.0In adjustment window, allowing you to fine-tune the rated current to match real load conditions. This helps reduce nuisance trips while maintaining protection accuracy—especially useful for systems with changing loads or future capacity upgrades.
Multiple frame sizes and ratings support both branch and main distribution protection, making selection easier for different project scales.
The series is available in 3-pole and 3-pole + neutral (3P+N) versions to fit common industrial and commercial wiring practices and panel layouts.
TM Adjustable MCCBs can be equipped with practical accessories such as auxiliary contacts, alarm contacts, shunt trip, undervoltage release, and operating mechanisms, enabling signaling, remote control, interlocks, and automation-ready distribution.
Designed for straightforward mounting and wiring, this product range helps panel builders improve assembly efficiency and keep system layouts clean and serviceable.
TM Adjustable MCCBs are commonly selected for:
Main and sub distribution boards
Industrial power panels and switchgear
Motor feeders and large load branches
Special distribution boxes and cabinet systems
