HHFD62B070 - 70Amp Circuit Breaker

HHFD62B070 - 70Amp Circuit Breaker

The Siemens HHFD62B070 is a 2-pole, 70-amp SENTRON molded case circuit breaker built on the FD frame and rated for your applications up to 600V. It uses a thermal-magnetic trip unit and carries an interrupting rating of 25kAIC at 600V and 100kAIC at 480V, giving electricians and maintenance teams a clearly defined set of electrical characteristics to match against the equipment already in service. This breaker includes line- and load-side TA1FD350A lugs, with conductor ranges of 6 AWG to 350 kcmil copper and 4 AWG to 350 kcmil aluminum.

Key Features and Benefits

• 70A current rating – Designed for compatible circuits and equipment requiring a 70-amp molded case circuit breaker.
• 2-pole configuration – Provides the two-pole arrangement required by applicable electrical distribution systems.
• 600V rating – Suitable for systems designed around a breaker with this voltage rating.
• Thermal-magnetic trip unit – Uses thermal and magnetic trip functions as part of the breaker’s specified protective design.
• FD frame – Matches compatible equipment built around the corresponding FD-frame form and dimensions.

Where It Works Best

The Siemens HHFD62B070 70A 2-pole circuit breaker works best in compatible electrical distribution equipment that specifically requires an FD-frame breaker with a 70A rating, 600V capability, 25kAIC interrupting rating at 600V, thermal-magnetic trip unit, and the specified line-and-load lug configuration. It is a particularly useful choice for maintenance and form, fit, and functional replacement projects where the existing equipment is already designed around these characteristics.
