Siemens | HQ2100BH | Circuit Breaker | 100A | 2-Pole | 240V

Siemens HQ2100BH 100A 2-Pole 240V Circuit Breaker is built for reliability in maintenance, retrofit, and replacement projects where exact compatibility matters. With the HQ2100BH part reference, this breaker is designed to match the specifications of Siemens panels, helping you avoid tracing mismatches and field-fit issues.

• Amperage: 100A
• Poles: 2-Pole
• Voltage: 240V
• Reference: HQ2100BH

Why this matters: the two-pole design protects both live conductors in a 240V circuit, ensuring simultaneous disconnection for safer operation and proper protection of connected equipment. This explicit 100A rating and 240V specification align with standard Siemens panel configurations, reducing the risk of nuisance trips caused by incompatible replacements.

Key benefits and differentiators:

• — built to align with Siemens panels that require HQ2100BH, minimizing installation guesswork and panel downtime.
• Reliable protection — a robust two-pole mechanism designed to handle typical 240V circuits found in home, commercial, and light industrial settings.
• Maintenance-ready — an exact-fit replacement that simplifies retrofits and service maintenance by preserving existing wiring and panel layout.
• Durability — engineered by Siemens to endure repeated cycling and real-world electrical demand, helping extend the life of the panel system.

Ideal use scenarios:

• Residential panels undergoing service upgrades or hardware refresh where a 100A, 2-pole, 240V style breaker is required.
• Commercial equipment circuits that demand dependable overcurrent protection with precise Siemens compatibility.
• Retrofits or replacements in existing Siemens installations where the HQ2100BH reference is the best match for continued performance.

Practical tips for framing and installation (safety and performance in mind):

• Always verify fit and ratings against your panel labeling before ordering. The HQ2100BH reference is the most reliable compatibility check.
• Power down the service and follow local electrical codes during replacement or retrofit work.
• Inspect the bus bar and terminal connections for cleanliness and corrosion before securing the new breaker.
• Use proper torque on terminal screws as specified by Siemens to ensure a solid, ongoing connection.
