Description
The Allanson 421-BT332 is an OEM ferromagnetic ignition transformer built for reliable spark energy in multi-burner oil burner and HVAC combustion applications. It features a 120 VAC primary and 10,000 VAC secondary output with ~23 mA current and a ~250 VA constant-duty rating — ideal for providing strong and consistent ignition performance across residential, commercial, and light industrial systems. The unit’s midpoint-grounded, double-pole design with high-temperature wiring runs cooler and quieter under load, and it complies with American and European EMI/RFI noise suppression standards. This model commonly replaces legacy parts such as Webster 312-25AB0202 and France LGFV ignitors.
