Meet Siemens ED43B025L — a compact 25 A, 480 V, 3-pole molded case circuit breaker designed to protect your branch circuits with precision. Built for reliable performance in panelboards and load centers, this unit balances robust protection with efficient panel-space usage, making it a smart choice for modern electrical distributions.

Why choose ED43B025L

  • Compact molded case design maximizes usable space in panelboards and load centers, enabling neater, more organized electrical distribution.
  • Thermal-magnetic trip unit delivers stable overload protection with fast magnetic response for short-circuit events, helping limit damage and downtime.
  • Three-pole configuration ensures simultaneous disconnection of all three phases, improving safety and fault clearance in 480V three-phase systems.
  • OEM-compatible designed to work with matching Siemens OEM load centers and panelboards, simplifying installation and coordination.
  • Versatile across settings suitable for residential, commercial, and light industrial applications where 480V distribution is present.

Technical specifications at a glance

Parameter Specification
Manufacturer Siemens
Part Number ED43B025L
Type Thermal-magnetic molded case circuit breaker
Amperage Rating 25 A
Voltage Rating 480 V
Number of Poles 3
Application Branch circuit overcurrent and short-circuit protection

Practical use cases

  • New installations in 480V three-phase facilities—data centers, manufacturing floors, and large office complexes—where reliable protection is critical.
  • Panelboard upgrades or replacements in Siemens-compatible systems to restore dependable branch circuit protection.
  • Renovations and retrofits where space efficiency matters but protective performance cannot be compromised.

What problems this solves

The ED43B025L pairs space-efficient design with a dual-mode protection approach. The thermal element guards against nuisance tripping due to gradual temperature rise, while the magnetic element responds rapidly to high fault currents. The result is predictable, repeatable protection that keeps wiring and equipment shielded from damage, reducing maintenance costs and downtime in busy electrical environments.

Installation and compatibility tips

  • Verify panelboard compatibility with Siemens ED43B025L and ensure alignment with matching OEM load centers for optimal trip coordination.
  • Confirm your system is configured for 480V and that a 25 A protective rating matches the circuit’s load profile to balance safety and performance.
  • Plan for three-phase protection continuity—the 3-pole design is intended to guarantee all phases trip together in fault conditions.
