What is ETA circuit breaker?
E-T-A presents the next generation of the 3120 circuit breaker/switch combination. It’s even easier and safer to operate, and offers significantly improved water and dust protection. It is a time and cost saving solution for equipment and machines.
What is a time delay circuit breaker?
Circuit breaker short-time-delay (STD) mechanisms allow an intentional delay to be installed on low voltage power circuit breakers. Short-time-delays allow the fault current to flow for several cycles, which subjects the electrical equipment to unnecessarily high mechanical and thermal stress.
Are RV breakers the same as house breakers?
In the typical home, both sides of such a dual breaker will be of the same value, but not necessarily so in an RV. You can often get a suitable replacement breaker for a single or double of the same value at the hardware store, but if you can’t find what you need, by all means, visit an RV supplier.
What is the difference between thermal and magnetic circuit breakers?
The mechanism that trips the breaker with the magnetic breaker is more responsive to excessive current flow, while the thermal responds to heat, which is only indirectly related to current flow. Under normal operating conditions both types are responsive to over-current events.
What type of circuit breaker provides a time delay feature?
When the circuit is required to be provided with a protective device for overload type conditions, a thermal time delay element is typically provided. The thermal element provides a time delay function called Inverse.
What kind of breaker do I need for an RV?
What size breaker do I need for a 30 amp RV plug? A 30 amp Recreational Vehicle plug must actually be used with a 30 amp breaker. You could also plug it into a 15 or 20 amp breaker, but you run the risk of damaging your RV if you utilize more than the ranked power the circuit/outlet has been designed for.

What is a thermostatic circuit breaker?
Thermal circuit breakers (circuit protectors, resettable fuses, circuit breakers for equipment protection) are ideally suited to overload protection of motors, transformers, magnetic valves, on-board electrical systems and low voltage lines.
What are the dimensions of a thermal reset circuit breaker?
Single pole thermal reset circuit breaker in a miniaturised design intended for threadneck or snap-in mounting, dimensions: 32.0 x 27.0 x 13.6 mm. It’s only a circuit breaker.
What is the trip time of thermal circuit breakers?
The trip time of thermal circuit breakers depends on the overload current. The heating effect of current heats up the bimetal or hot wire until the tripping point is reached and the breaker provides genuine physical contact isolation.
