Hager SFL225 25A 2 Pole Modular Changeover Switch Bottom Common Point

Description

Two poles, two supplies, one changeover.

The Hager SFL225 is a 2 pole, 25A modular changeover switch that selects a two-wire circuit between two power sources. With its common point at the bottom, it gives a clean manual transfer between supply A and supply B across both poles, making it well suited to caravans, RVs and modular sub-boards where a compact two-pole changeover is needed.

What Is a 2 Pole Changeover Switch?

A two-pole changeover switch selects both conductors of a single-phase circuit, typically active and neutral, between two power sources at once. The SFL225 places the common point at the bottom, so the shared connections land below and the two selectable sources connect above. It is a manual switch, giving a positive, visible position for each supply.

Compact Sub-Board and RV Fit

At two modules wide, the SFL225 fits neatly into a distribution board or a caravan sub-board without consuming space. It mounts on standard 35mm DIN rail, accepts rigid conductors up to 16mm2 through screw terminals, and is rated for utilisation categories AC21 and AC22 at 25A, covering resistive and mixed inductive loads.

Built to Last

Rated for 200,000 mechanical operations and 25,000 electrical operations at nominal load, the SFL225 is built for repeated switching over a long service life. An operating temperature range of -20 to 50 degrees Celsius suits it to a range of Australian installation environments.

Q: What does the Hager SFL225 do?
A: It is a two-pole manual changeover switch that selects a two-wire circuit between two power supplies, with the common point at the bottom, rated 25A at 230V AC.

Q: What size cable can the SFL225 take?
A: Its screw terminals accept rigid conductors from 1.5 to 16mm2 and flexible conductors from 1.5 to 10mm2, tightened to 1.8Nm.

Q: What is the difference between the SFL225 and the SFT225?
A: Both are 2 pole 25A changeover switches. The SFL225 has a bottom common point and no centre-off; the SFT225 is centre-off with an OFF isolating position and a top common point.
