Compliat with NEMA AB‐1. Climatic condition according to IEC/EN 60947 - 1 Annex Q, Cat. F subject to temperature, humidity, vibration, shock and salt mist.
Electronic protection unit with rotary knobs for regulation of thermal current and magnetic current. Thermal protection within range of 0,4 - 1,0 of the rated current. Magnetic protection within range of 1,5 - 10 of the rated current.
Can be equipped with releases (undervoltage and shunt releases) and auxiliary contacts. Can used with rotary handles or motor operator. Locking accessories are available.
Has diffent type of possible connection accessories: cage terminals, spreader and rear terminals. Is available also in a plug-in version (circuit breaker fitted with special terminals and mounted on a plug-in base) or in a draw-out version (a plug-in version fitted with a "Debro-lift" mechanism which can be used to withdraw the breaker while keeping it on its base)

DPX3 platform has been developed to give a new solution of protection devices for a more precise approach in power installations in order to offer the correct answer for different project needs.

DPX3 platform provide a complete "project" approach in premium market segment, offering a range completely suitable for high power application

DPX3 630 is the answer for the competition in the project sub-segment. A unique size for all versions (thermal magnetic, electronic with or without measure). Earth leakage fetures can be achieved by adding a dedicated module at the bottom of the breaker itself.
