Overview
EN 3841-407:2004 - Aerospace series - Circuit breakers - Test methods - Part 407: Temperature variation - is a European/AECMA-STAN test method that specifies how to verify a circuit breaker’s ability to withstand temperature variation. Published and approved in 2004 and intended to be used together with EN 3841-100, this standard defines mounting and test procedures for environmental temperature cycling of aerospace circuit breakers and references the environmental test profiles in ISO 7137.
Key topics and requirements
- Scope: Verifies circuit breakers’ resistance to temperature changes that occur in airborne equipment environments.
- Mounting: Devices under test are mounted on a support inside a temperature chamber and remain connected to an external power supply.
- Test condition: Circuit breakers are tested in the ON position.
- Procedure reference: Temperature variation testing is performed in accordance with ISO 7137, test procedure 1.2 (without altitude).
- Specification-driven parameters: The technical specification or product standard must define:
- Category of the test and applicable temperature profile
- High and low operating temperature extremes
- Number of thermal cycles and load conditions during cycles
- Any additional performance tests to be applied after or during cycling
- Acceptance: Performance and pass/fail criteria are those specified in the product technical specification and applicable EN/industry standards.
Applications and who uses it
EN 3841-407 is practical for:
- Aerospace component manufacturers qualifying circuit breakers for aircraft and spacecraft environments
- Test laboratories performing environmental and qualification testing on electrical protection devices
- OEM systems engineers and procurement teams specifying component qualification criteria
- Certification bodies and quality assurance teams verifying conformity to aerospace environmental requirements
Practical uses include establishing supplier test plans, validating design robustness to thermal cycling, reproducing flight/ground thermal conditions for qualification, and supporting part acceptance and certification activities.
Related standards

- ISO 7137 - Aircraft - Environmental conditions and test procedures for airborne equipment (test procedure 1.2 referenced)
- AECMA-STAN / CEN implementation guidance and national adoptions across CEN member bodies
By following EN 3841-407:2004 together with EN 3841-100 and ISO 7137, organizations ensure consistent, repeatable temperature variation testing of aerospace circuit breakers that aligns with European and industry expectations.
