Eaton CHSPT2ULTRA Ultimate Surge Protection (Type 2) Review

As far as surge protectors are concerned, Eaton needs little introduction. The surge protection devices produced by Eaton have continued to gain popularity and top honors since Eaton acquired Cutler-Hammer in 2012. Among Eaton’s most popular models of surge protection for the whole house is this CHSPT2ULTRA.

It is important to decide which appliances you must protect from power spikes and surge transients before choosing a surge protector for the entire house. A surge protector (Type 3 SPD) at home will protect your whole house from surges.

Surge suppressors have already been available for three editions, each delivering a high level of performance, functionality, and reliability. Check out the full review of this surge suppressor before purchasing.

Eaton CHSPT2ULTRA Type 2 – Benefits & Features

Capacity to withstand surge current in the event of an overload (MSCC)

To ensure the protection of your whole house against surges, you need at least 30kA (30,000 amps). Surge suppressors are most commonly found in 30kA capacities, which are well within the IEEE guidelines. CHSPT2ULTRA by Eaton is by far more powerful than that requirement, boasting 108kA. This device would probably be more potent than most offered in the market if it had surge capacity.

Protection methods

Several brands offer different modes of surge protection, so keep an eye out when looking for surge protection devices. Eaton CHSPT2ULTRA meets all the below requirements for comprehensive surge protection.

The Line to Neutral function (L-N)

  • A line to ground (L-G).
  • The line to Line (L-L).
  • It stands for Neutral to Ground (N-G).

The Schneider Electric model Square D HEPD80 is equipped with all the above protection modes.

Short Circuit Current Rating (SCCR)

The 22kA SCCR that comes with the CHSPT2ULTRA is decent considering that the short circuit current is seldom as high as that emitted by power spikes. Thus, having a 22kA is already well above the average for other brands.

Voltage Clamping

After a surge protection device has blocked a power surge, clamping voltage is the residual voltage that can pass through it. As you can see from Eaton’s VPR, it is apparent that Eaton is more capable of handling power surges than other brands.

L-N: 600V
L-G: 600V
L-L: 1000V
N-G: 800V

Enclosures of type 4 NEMA

For electrical enclosures, NEMA Type 4 is a good standard. In addition to keeping dirt, water, and other substances out, they are great for use indoors and outdoors.
