Technical Features

• High Breaking Capacity (S300P / S200P Standard): Engineered for demanding industrial and heavy commercial installations, providing an enhanced short-circuit breaking capacity (up to 25 kA in accordance with IEC/EN 60947-2).

• Rated Current & Poles: Features a 16 A rated current across 4 Poles (4P), ensuring complete multi-phase and neutral isolation (three phases plus neutral) simultaneously during a fault.

• Type C Tripping Characteristic: Magnetic trip release operates between 5 and 10 times the rated current, preventing nuisance trips from moderate surge currents while reacting rapidly to short circuits.

• DIN Rail Mounting: Built for quick, secure snap-on installation onto standard 35 mm TH35 DIN rails within electrical panels and distribution boards.

• Robust Terminal Architecture: Equipped with fail-safe, bi-directional cylinder-lift terminals that ensure secure conductor clamping and prevent improper cable insertion.

Applications

• Three-Phase Plus Neutral Commercial Distribution: Ideal for multi-phase commercial sub-panels supplying mixed loads, office distribution boards, and lighting systems requiring 4-pole switching.

• Industrial Machinery & Equipment Feeds: Deployed in industrial automation panels and machinery control circuits where full multi-phase and neutral disconnection is mandated for safety.

• HVAC & Building Automation: Protects three-phase air handling units, commercial ventilation systems, and complex control panels with high prospective fault current levels.

Buyer Guidance

• Verify Pole Configuration: Ensure your installation specifically requires a 4-pole (3 phases + neutral or 4-pole switched) device rather than a standard 3-pole breaker.

• Match Breaking Capacity: Confirm that the high-performance S300P series specifications align with the prospective short-circuit current calculations of your main or sub-distribution board.

• Professional Installation: Due to the multi-phase, high-amperage nature of industrial distribution equipment, installation should always be performed by a certified electrical professional in compliance with local safety codes.
