GE THHQB32070 - 70 A, 240 V, 3-Pole Bolt-On Circuit Breaker | AmpState

GE THHQB32070 — a 70 A, 240 V, 3-pole bolt-on molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters. From AmpState, this GE unit blends robust construction with precise protection, engineered to keep critical electrical systems running smoothly in a variety of settings.

Why this breaker stands out

• Secure bolt-on mounting creates a rigid, vibration-resistant bus connection, reducing the risk of loose connections and ensuring consistent performance in environments with equipment movement or vibration.
• Thermal-magnetic trip unit provides stable, repeatable protection by quickly responding to overloads (thermal) and instantaneous short circuits (magnetic), helping minimize damage to circuits and connected equipment.
• OEM-compatible design is matched to GE’s own loadcenters and panelboards, streamlining installation and ensuring proper fit, labeling, and coordination with existing protection schemes.
• Versatile for multiple industries suitable for residential, commercial, and light industrial applications where reliable three-phase protection is required.
• Durable molded-case construction built to withstand the rigors of daily operation, heat dissipation, and field conditions, while delivering predictable performance over time.

Ideal use cases

• New or retrofit panelboard installations in commercial spaces that require solid 3-pole protection for three-phase circuits.
• Upgrading circuits in light industrial equipment where dependable short-circuit protection can prevent costly downtime.
• HVAC, motors, pumps, and lighting systems in residential or small-business environments where vibration and temperature changes are common.
• Any application demanding a bolt-on solution that stays securely connected to the bus bar under dynamic load conditions.

How it protects your system

The GE THHQB32070 uses a thermal-magnetic mechanism to deliver two layers of protection in one device: the thermal element senses and responds to prolonged overloads, while the magnetic element provides a fast, instantaneous trip for short circuits. This dual action helps safeguard wiring, components, and downstream devices, reducing the likelihood of further damage and shortening outage times after a fault.
