Mitsubishi 10kW Electric Heat Strip for SVZ Medium-Cabinet Air Handlers, EH10-SVZ-M
The Mitsubishi EH10-SVZ-M is the highest-output electric heat kit in the SVZ air handler lineup. It delivers 10 kW at 240V (7.5 kW at 208V) through two 5kW stages and is built for the medium-cabinet SVZ-KP30NA and SVZ-KP36NA, as well as the R454B Mitsubishi SVZ-AP36NL 36K BTU air handler. The 21-inch-wide module matches the larger cabinet's supply opening and ships with a 60A factory breaker. It's a strong choice for 2.5-ton and 3-ton Mitsubishi ducted heat pump systems in larger homes and light-commercial spaces that need serious backup and emergency heat.
Is a 10kW Heat Strip the Right Size?
On the medium SVZ cabinet, the 10kW kit is the top option above the EH05-SVZ-M and EH08-SVZ-M. It fits buildings with a larger heat loss, homes in regions with extended sub-freezing weather, and owners who want enough emergency heat to keep the space comfortable if the outdoor unit is out of service.
Before selecting 10kW, compare the building's design heat load with the heat pump's output at your winter design temperature, and confirm the electrical service can support a 50A–60A circuit. Ducts in unconditioned spaces, older or leakier construction, and large open floor plans all push supplemental heat needs higher. Tight, well-insulated homes in milder climates may be better served by a smaller medium-cabinet kit.
Ideal for: SVZ-KP30NA, SVZ-KP36NA and SVZ-AP36NL systems serving larger single-family homes, multi-story layouts, cold-climate properties, small retail spaces and offices that need full-strength emergency heat.
Need a small-cabinet kit? The 10kW EH10-SVZ-M fits medium SVZ cabinets only. For SVZ-KP18NA and SVZ-KP24NA air handlers, choose the Mitsubishi 8kW Heat Strip, EH08-SVZ-S, or the 5kW EH05-SVZ-S for the SVZ-KP12NA.
Recommended heat kit applications are general guidelines only. Actual supplemental heat requirements depend on insulation, climate, heat pump capacity, duct design, and available electrical service. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

The EH10-SVZ-M is sized specifically for the wider medium SVZ cabinet, with a 21-inch body and an 18-13/16-inch duct opening. Two 5kW stages let the air handler add heat gradually, and the built-in 60A breaker provides a convenient service disconnect right at the unit. The heater harness comes pre-bundled in the SVZ cabinet, which keeps installation simple for contractors finishing a Mitsubishi heat pump system.

Frequently Asked Questions
Is there a 10kW heat strip for the small SVZ cabinet?
No. Mitsubishi offers the 10kW kit only in the medium-cabinet EH10-SVZ-M version. Small-cabinet SVZ air handlers top out at the 8kW EH08-SVZ-S.
What does the "M" in EH10-SVZ-M stand for?
The "M" designates the medium SVZ cabinet. Medium kits are 21" wide with an 18-13/16" duct opening. The "S" small-cabinet kits are 17" wide with a 14-13/16" opening.
How many amps does the EH10-SVZ-M draw?
The heater alone draws 41.7A at 240V and 36.1A at 208V. With the air handler motor included, total current is 45A at 240V and 39.4A at 208V, with an MCA of 56.2A and 49.3A respectively.
What heating output can I expect from the 10kW kit at 208 volts?
At 208V the EH10-SVZ-M produces 7.5 kW, or about 25,590 BTU/h. At 240V it reaches its full 10 kW rating.
What smaller heat kits fit the SVZ-KP30NA and SVZ-KP36NA?
Besides the EH10-SVZ-M, Mitsubishi approves the medium-cabinet EH05-SVZ-M (5kW) and EH08-SVZ-M (8kW) for these air handlers when less supplemental heat is needed.
Can an auxiliary heat lockout be added to the EH10-SVZ-M?
Yes. Mitsubishi lists the ETC-211020-MIT auxiliary heat lockout as an optional accessory. It can prevent the electric heat from running above a selected outdoor temperature so the heat pump carries the load.
