Siemens Q12000S01 120-Volt Shunt Trip MP-T 20-Amp Breaker
This UL-listed breaker doubles as a standard 120-volt MP-T device and includes a 120-volt shunt trip. Its design allows external tripping triggered by a safety or control system, enhancing isolation during emergencies. The unit is a single-pole solution that occupies the space of two poles, delivering compact external trip capability in a familiar Siemens MP-T format. Suitable for controlling circuits on simplified, low- and mid-current applications where external activation is required.
Siemens Q22000S01 120/240-Volt Shunt Trip MP-T 20-Amp Breaker
This double-pole breaker handles 120/240-Volt circuits and includes a shunt trip feature for externally triggered disconnection. It occupies the space of three poles in a standard panel, offering enhanced protection for multi-wire branch circuits and critical loads. The device is UL-listed and designed for reliable operation in electrical distribution systems requiring remote shutdown capability, making it appropriate for safety-critical environments and life-safety systems where fast isolation is required.
Siemens Q26000S01 120/240-Volt Shunt Trip MP-T 60-Amp Breaker
This 60-amp MP-T breaker provides robust protection with a 120-volt shunt trip, enabling external disconnection for high-current circuits. The unit is designed to fit the MP-T family and occupies the space of three poles. Its UL listing supports use in commercial and industrial panels requiring external control signals for safety interlocks, emergency shutdowns, and automated safety systems. Because it is a higher-amp device, ensure your panel and wiring are rated for the increased load and cabinet clearance is sufficient for installation.
DIHOOL DC Circuit Breaker Shunt Release for Remote Control
This device functions as a shunt release for remote circuit breaker control, using a 24V DC signal to trigger tripping. It is compatible with a range of circuit breakers rated for 100 to 320 amps and is suitable for remote isolation in power distribution, solar, battery, UPS, and similar systems. Users should observe the voltage tolerance and ensure long-term power stability, as the release can be damaged by extended continuous power supply. It provides a flexible option for adding external trip capability to compatible breakers.
Shunt Trip Circuit Breaker 3P 100 Amp 240Vac (Square D)
This three-phase shunt trip breaker from Square D offers a robust solution for larger systems needing external shutdown capability. It is manufactured for industrial applications, with a focus on safe rapid disconnection under control signals. While rated at 100 amps, it provides a benchmark for understanding triple-pole shunt-trip configurations in higher-current environments. Ensure compatibility with your panel style and mounting provisions, and verify control voltage requirements match your safety system design.
Shunt Trip Circuit Breaker 2P 100 Amp 120/240Vac
This two-pole 100-amp shunt-trip breaker accommodates 120/240-volt systems with external tripping options. It is suitable for commercial and industrial applications where rapid isolation is required by a safety system. As with other shunt-trip devices, confirm control voltage compatibility and that the panel and conductor sizing meet the amperage demands of the connected load.
Buying Guide: Key Considerations For Shunt Trip Breakers
When selecting a shunt trip breaker, consider the following factors to ensure proper fit and safe operation:
- Voltage and current rating: Match the service voltage (120V, 240V, or 120/240V) and the breaker’s amperage rating to the circuit and panel specifications. Higher amp ratings require appropriate conductor sizing and panel space.
- Shunt trip type and voltage: Confirm the external trip trigger voltage (common options include 24V DC signals). Check compatibility with the control system that will initiate the remote trip.
- Pole configuration: Choose single-pole, double-pole, or three-pole configurations based on the circuit layout and the need to simultaneously disconnect multiple conductors.
- Panel compatibility: Ensure the breaker’s MP-T or other family designation aligns with your panel make and model. Incompatibilities can affect fit and performance.
- Physical footprint: Some shunt-trip devices occupy more space (three poles versus two), so assess panel space, bus bar clearance, and mounting requirements.
- Safety and certifications: Look for UL listings and any regional certifications relevant to your installation site and electrical codes.
- Remote control reliability: For critical safety systems, evaluate the control circuit design, potential false trips, and environmental considerations such as temperature and vibration.
- Retrofit potential: If upgrading an existing system, verify whether a shunt release accessory can be added or whether a new breaker is required.
- Maintenance and documentation: Plan for testing intervals, maintenance records, and availability of replacement parts or accessories.
These guidelines help compare options across brands, including Siemens MP-T family breakers and Square D shunt-trip devices, as well as dedicated shunt-release modules. Where exact 200-amp shunt-trip breakers are scarce, evaluate near-term equivalents (such as multi-pole, 100 A or 60 A devices) for your system’s safety objectives and plan upgrades accordingly.
