HHED63B020L - 20Amp Circuit Breaker

HHED63B020L - 20Amp Circuit Breaker

The Siemens HHED63B020L is a 20-amp, 3-pole SENTRON molded case circuit breaker designed for electrical systems requiring an ED-frame breaker with a thermal-magnetic trip unit. The breaker meets UL 489 and IEC 60947-2 standards and is well suited for maintenance and replacement situations where the equipment calls for the HHED63B020L or its specific electrical and physical characteristics. When you're replacing an existing molded case circuit breaker, verify the complete catalog number along with the frame, amperage, number of poles, voltage, interrupting rating, lug configuration, wire range, and dimensions. Matching these details helps preserve the intended form, fit, and function of the electrical system.

Key Features and Benefits

• 20A, 3-pole configuration supports electrical equipment designed for this specific breaker arrangement.
• Rated up to 600VAC for compatible low-voltage electrical applications.
• Thermal-magnetic trip unit provides the specified overcurrent protection characteristics of the HHED63B020L.
• ED-frame construction helps technicians identify the correct physical and electrical configuration for replacement applications.
• Line- and load-side SA1E025 lugs distinguish this configuration from similar breakers with different terminal arrangements.
• Accepts 14–10 AWG copper and 12–10 AWG aluminum conductors.
• Compact 3 × 6.53 × 3.92-inch dimensions make it easier to confirm physical compatibility with existing equipment.
• Meets recognized UL 489 and IEC 60947-2 standards.
