The electrical contacts are extremely heavy and capable of handling smaller currents in the electrolyzer range with ease.
They'd be an excellent choice for this application if their coil resistance wasn't so low. It is typically 4 ohms so it draws quite a lot of current (about 3 amperes) and dissipates about 36 watts. In time it would become very hot and possibly damaged.
A3holerman is correct, the automotive 30 ampere relay is a better choice as it only draws about 160 milliamperes of coil current and will tolerate continuous energizing for many, many hours.
