sds-25 chint 25a 450v dc isolator
CHINT SDS-25 is a 25 A IP65 enclosed rotary DC isolator rated for DC systems up to 450 V and supplied with four weatherproof cable glands.
Why Choose the CHINT SDS-25 DC Enclosed Rotary Isolator?
The CHINT SDS-25 is a robust and weatherproof DC enclosed rotary isolator designed to provide safe manual isolation of direct-current electrical circuits. Rated at 25 A and suitable for DC systems up to 450 V DC, it provides a practical isolation solution for electrical installations where dependable local disconnection is required.
The SDS-25 is supplied in a durable IP65 enclosure, providing protection against dust and water ingress for demanding installation environments. Its enclosed construction and rotary operating mechanism make circuit isolation straightforward, while the switch can accommodate up to three lock-off padlocks to help prevent unauthorised or accidental operation during maintenance.
For convenient installation, the SDS-25 is supplied with four weatherproof cable glands. Combining a 25 A current rating, operation at up to 450 V DC and weather-resistant construction, it is well suited to DC power, renewable-energy and industrial electrical applications.

Reliable Isolation for DC Electrical Systems
DC isolators provide a means of manually disconnecting electrical circuits so equipment can be isolated when required for maintenance, inspection or servicing. A clearly operated local isolator helps establish a defined disconnection point between equipment and its DC power source.
The CHINT SDS-25 combines this isolation function with an IP65 enclosure suitable for demanding environments. Its lock-off capability provides additional control during maintenance, while the included weatherproof glands simplify cable entry into the enclosure.
Typical Applications
- DC electrical distribution systems.
- Renewable-energy and solar PV installations where its electrical ratings are suitable.
- Battery and DC power systems.
- Industrial control and automation equipment.
- Outdoor and weather-exposed electrical installations.
- Local isolation of DC-powered equipment.
