Hager ESC227 Modular Contactor 25 A 1NO+1NC 230 V AC Coil
The Hager ESC227 modular contactor is a control device for the DIN rail that makes it possible to open and close an alternating current circuit remotely. It takes up a single module (17.85 mm) and is installed in the distribution board, downstream of the protective devices, where loads have to be driven by a push button, a programmable time switch, a thermostat or an energy management system.
It has two power contacts: one normally open (NO) and one normally closed (NC), with a rated current of 25 A in utilisation categories AC-7a and AC-7b (resistive loads and motors for household and similar use). The coil is supplied at 230 V AC 50 Hz. The NO+NC configuration allows switching logics, for example alternating between two loads or automatically excluding one load when another is activated, a typical function in load management in photovoltaic and storage systems.
Key features
A single DIN moduleJust 17.85 mm wide: it takes up one modular space in the switchboard and leaves room for the other protective devices.
NO + NC contactsOne normally open and one normally closed contact make it possible to control one load and exclude another at the same time.
25 A in AC-7a/AC-7bSized for the household and similar loads, both resistive and with a motor, covered by utilisation categories AC-7a and AC-7b.
230 V AC controlThe 230 V 50 Hz coil is driven directly by a push button, a timer, a thermostat or the relay output of an energy management system.
Long life100,000 mechanical operations and 30,000 electrical operations declared by the manufacturer.
Low dissipationTotal power losses of 2.50 W at rated current, with limited heating of the switchboard.
