HFD62B090L - 90Amp Circuit Breaker

HFD62B090L - 90Amp Circuit Breaker

The Siemens HFD62B090L is a 90 Amp, 2-pole Sentron molded case circuit breaker built around the FD/HFD6 frame for compatible commercial and industrial electrical equipment. For an existing system designed around this HFD6 configuration, the HFD62B090L gives you the specified frame, amperage, pole count, voltage, lug arrangement, and interrupting ratings needed to maintain the intended form, fit, and function.

Key Features and Benefits

• 90A, 2-pole configuration for electrical equipment designed around these exact ratings.
• FD/HFD6 frame helps maintain the required physical configuration in compatible systems.
• Rated for applications up to 600VAC.
• Thermal-magnetic trip unit provides the specified overload and short-circuit protection characteristics.
• Standard 40°C breaker configuration.
• Includes TA1FD350A line- and load-side lugs, an important distinction when matching an existing breaker.
• Accepts 6 AWG–350 kcmil copper conductors.
• Accepts 4 AWG–350 kcmil aluminum conductors.
• Meets UL 489 and IEC 60947-2 standards.

Material Compliance and Certifications

The Siemens HFD62B090L configuration is associated with UL 489 and IEC 60947-2 requirements for molded case circuit breakers. These standards provide useful compliance checkpoints when evaluating the breaker for a particular electrical system or replacement application.

Where It Works Best

The HFD62B090L makes the most sense in commercial and industrial electrical equipment designed for a 90A, 2-pole FD/HFD6 molded case circuit breaker with line- and load-side lugs. It is especially relevant for maintenance and replacement work involving existing or legacy equipment where changing the breaker style isn’t the goal—the priority is keeping the required frame, electrical ratings, terminal arrangement, and physical fit consistent with the original system.
