A Zealot is more of a monk/psychic hybrid than a paladin, as he trains in martial arts and has the ability to call forth those psionic powers. The reason he can do that is because the suit he is wearing allows him to focus his willpower and mind into creating it through the crystals on his arms.

The lore behind the Zealots of the Templar Caste:

For millennia the Templar caste of the Protoss have defended their people from threats both internal and external, dedicating their long lives to the pursuit of martial perfection. Zealots are peerless templar warriors who have yet to achieve the uppermost ranks of the Khala. Ever eager for battle, zealots train constantly to attune themselves more closely to the Khala's disciplines and prove themselves worthy of advancement. They exemplify the unbridled ferocity of the protoss at war.

The formidable physique of a zealot is further enhanced by cybernetic implants and their coveted power suit. Yet a zealot is far more than the technology he bears. Each Zealot is trained for decades in hand to hand combat, tactics, pain tolerance and martial discipline. Zealots are taught to hate their enemies with a white hot passion and to hunt them down without mercy.

All protoss have some psionic ability and zealots focus their minds exclusively on the pursuit of war. Focus crystals in their heavy forearm units enable zealots to channel their strength of will into blades of pure psionic energy - their primary melee weapons. Using a limited form of precognition, zealots can even predict enemy movements striking, with deadly accuracy and dodging attacks by inches.

Some Zealots have even developed the ability to turn their body into pure energy for a few microseconds. This allows them to move at lightning fast speeds and strike suddenly against an enemy that thinks they are out of range.

In recent times the zerg invasion of the protoss homeworld of Aiur forced its evacuation to the distant dark templar world of Shakuras. The Templar caste as a whole, and the zealots in particular, seethe with shame at this dishonor. Many and loud are the voices raised demanding a return to Aiur, cradle of the protoss civilization. The zealots have thrown themselves into an even more rigorous program of training in preparation for the glorious day when their services will be called upon once more.

Highlighted the part about their suit and their weapons.

If you are looking for the supportive character, aka paladin, of SC among the Protoss you'd better look for the High Templar, as they don't have any kind of direct damage, only spells they can summon up.

The rogue class among the Protoss is quite possibly the Dark Templar, as they are constantly invisible, and can deal huge amounts of damage if you can't locate them fast enough. If they get in your base undetected they will swiftly destroy anything inside in a matter of minutes, perhaps even less.
