DD-Frame Series

Features

The DD-Frame is available in many configurations and can be built to specific requirements.

This rugged, versatile circuit breaker comes with 1 to 6 poles in AC and DC configurations, with a choice of trip characteristics.

Common configurations include a standard front handle and a recessed rocker actuator.

Metric and imperial stud terminals, plug-in (bullet) terminals, and screw and clip terminals are available.

Auxiliary switch and alarm (trip indication) options are available.

Custom versions can be built, with DIN-rail mounting and various other options.

The DD-Frame is made from high-quality thermoset materials for better electrical performance and mechanical durability.

A self-cleaning mechanism keeps the contacts clean and operation smooth for a longer service life.

DD-Frame HCR (high current rating)

A higher-current version for low-voltage applications: at 60 VDC it handles up to 125 A in 1-pole, 250 A in 2-pole and 300 A in 3-pole configurations.

DD-Frame breakers are CE and CCC compliant and carry VDE, cURus, EAC and CCC approvals.

They are also certified to UL 1077, UL 508, UL 489 and UL 489A, and comply with AS/NZS 60947-2.
